<objective> OSS maintainer fast-close workflow. PR number → three phases fire automatically: 1. **PR intelligence** — synthesize motivation from PR body, linked issues, thread; classify comments into action items 2. **Conflict resolution** — checkout PR branch (fork-aware), merge `BASE_REF`, resolve conflicts with contributor intent as priority lens 3. **Action item implementation** — implement each item as separate commit attributed to review comment, push to contributor's fork Result: conflict-free PR branch pushed to fork, ready to merge — no GitHub UI. **Core invariant — transparent, reversible**: every action = visible named git object. Use `git merge` (new commit, two parents), never `git rebase` (rewrites SHA, kills revert/cherry-pick). Each action item = own commit — granular revert always possible. Bare comment text → skip to Codex dispatch (Step 12). </objective> <inputs> - **$ARGUMENTS**: one of: - Omitted → **review-handoff mode**: auto-detect PR from most recent `.reports/review/*/review-report.md` - PR number (e.g. `42` or `#42`) or GitHub PR URL → **pr mode** - `report` (bare word) → **report mode**: latest review findings as action items; no GitHub re-fetch - `42 report` or `<URL> report` → **pr + report mode**: aggregate live GitHub comments + review report, deduplicated in one pass - Bare review comment text → **comment dispatch mode** (jumps to Step 12) - **`--no-challenge`**: optional — skip challenge gate per item; all selected items tre...
